I have just finished paying off my MR2 Mark 2 N/A WOOHOO!!! and would like to make some upgrades to improve it's performance. I am not expecting massive gains but what could I expect from a new exhaust system and induction kit? Any particular makes that are good? I don't want to spend silly money. I was looking at a Mongoose exhaust and K&N air filter. Any advice would be greatly appreciated.
